1. A concise explanation of the problem you’re experiencing.
Labels are not bad in Cesium 1.61, on mobile are perfect due to high display resolution and small size, but on PC screen are a bit hard to read if them are not big enough.
I know I could use a DOM in place of built-in labels, but it does not have sub-pixel position, so moving the map it does not move so well
